Preparing for the Cloud Robotics Hackathon

I recently learned about the Cloud Robotics Hackathon, and I'm trying to find out if my project idea is somewhat feasible. I'm an experienced programmer, but I am completely new to robotics and do not own a robot. So far I have registered for a MyRobots account and have registered my home computer as a robot (Stonehenge.) So far so good.

I would like to have a group of robots to communicate via MyRobots to react to one another a bit as if the were in the same room and had sensors and some way to track their relative position, orientation and speed.

I'm having problem grokking if such a thing is possible with the MyRobots API. Could I have a robot app receiving all the tracking info from the group of robots and dispatching between them? Or could one of the robot be a home computer "robot" to handle the information tracking and dispatching?

Or maybe one of the robot could have its program being subscribed to the other robot info, coordinate the information and to the dispatch. Or maybe each robot could broadcast its information to all the other robots.

To summarize the key points:
-Having some way to have a bunch of robot be part of the same group on MyRobots to communicate between themselves.
-Having some way to send position, orientation & speed information to the whole group (with relative virtual position) or to "head robot" or a desktop computer "robot" to determine which information to send to which robot.
-I forgot my third point
